| The effects of solvent and of system order on the redox properties of several substrates as well as on the kinetic demeanor of several ion radicals have been examined using aqueous, nonaqueous, and micellar media. The reaction of thianthrene cation radical with nitrate has been characterized in nonaqueous solvents while the electrochemistry of 16 nitrone spin traps and that of nitroso-tert-butane has been examined in both aqueous and nonaqueous media. The effects of micellar environments upon the oxidative electrochemistry of 10-methylphenothiazine and the reductive electrochemistry of nitrobenzene have been studied using anionic, cationic, and nonionic micelles. Results of these studies indicate that the functional behavior of micelle solubilized substrates is dependent upon the nature of the interaction between the substrate and the micelle. Finally, a "membrane" has been assembled on the surface of an optically transparent electrode by chemically modifying that surface with n-octadecyl hydrocarbon moieties. Adsorption of an amphiphile onto the modified surface results in a bilayer assembly attached to the electrode which can be used to mimic electrochemical processes within membranes. |
